4.1 Checking Normality
The normality of the distributions of all the tests used in the study was checked. Skewness and Kurtosis values for the distributions were calculated. Skewness is a measure which shows the extent to which a distribution deviates from symmetry around the mean, while Kurtosis shows the “peakedness” and “flatness” of a distribution. Skewness and Kurtosis values of zero indicate the data are perfectly normally distributed. However, values between ±1 are considered very good and values between ±2 are considered acceptable. Table 2 indicates the test of normality of the speeded cloze-elide test, multiple-choice cloze test, C-Test and reading comprehension. Table 2 shows most values are within the “very good” range and a few within the acceptable range (West, Finch, & Curran, 1995). Therefore, we can assume normality of the distributions for all the tests in the study.
